A example of Tornado application, service-api, data-store and oauth2 authentication.

This program just is written as study and demonstration. I beleave Tornado is best framework in such application.

• providing token for user who is logged in.
  • Users are autheticated by github oauth2. So oauth2 set-up is needed for this application in github as a resource owner.
• check its legal for inquired token by rest api.
• use sqlite3 forpermanent datastore.

• tornado 6.x
• sqlite3
• pycurl

• get client-id, client-secret by setting up your github oauth2 application.
• edit configs/token-service.yaml
• python3 tokenservice/tornado/server.py --config=configs/token-service.yaml

, and

• access to homepage in setting
• copy token string issued
• a example of use curl https://token-service/query/<github-login>/?token=...

• consider token life cycle.
• data-store robustness and scale-out.
• make more api to be useful processing with token...
